My present invention relates to a packing or road roller.

One of the principal objects of this invention is to provide a roller of this class which may be easily, quickly, and effectively operated,.and one which has a driving; transmission, and control unit which may be easily and quickly removed for repairs, and another such unit substituted, or which may be readily transferred from one roller to another.

Another important object of this invention is to rovide a novel and simple means of removably securing the unit supporting foundation or base on the main frame of the roller, simple means of operatively connecting the power unit to traction rollers of the machine, and novel and simple means of adjusting the unit, or the foundation for supporting the same, on the machine frame.

A further object of this invention is to provide a novelly constructed unit for a machine of this class which comprises a simple base and foot platform for housing the mechanism, but which provides ready access to all parts of the mechanism when the unit is removed from the machine.

A still further object of this invention is to provide simple construction and mounting of the control mechanism.

An important object also of this invention is to provide means of mounting the rollers on the machine so that they may be rigidly mounted and readily secured in place.

With these and other objects in view as will appear hereinafter, I have devised a packing or road roller having certain novel features of construction, combination, and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings, and to the characters of reference thereon which form a part of this application, in which-- Fig. 1 is a plan view of a road roller embodying my invention in a preferred form, portions thereof being broken away and in section to facilitate the illustration;

Fig. 2 is a side elevation thereof;

Fig. 3 is a fragmentary sectional elevation 5 Claims. ((31. 180-20) thereof taken through 3-3 of Fig. 2, showing the body I! carried by the frame I, and the rear rollers 3, consisting of a pair of axially spaced rollers. The latter rollers are exposed and are adapted to be rotated as a unit about a vertical axis at the center between the rollers. The rollers 3 are adapted for directing or steering the machine.

The rear rollers are embraced in a yoke 4, the

middle portion of which extends upwardly and and the roller is a continuous collar 6 and the portion outwardly from the collar and clamped in place by the cap is longitudinally split in four parts, as shown in Fig. 2. The split portions of the sleeves permit the same to be.clamped in the lower or supporting ends of the brackets. The shaft 5 is extended into the sleeves and is securely clamped therein when the sleeves are secured to the brackets by the caps 4*.

At each end portion of the shafts are axially spaced ball or roller bearings 1 and 8, each pair -of which supports one of the pair of rollers 3. 'The adjacently positioned inner bearings 8 are separated by a collar, 5 intermediate the.ends of the shaft.

The. body H is openintermediate its ends, forming. substantially a depression in which the power and transmission unit is removably mounted. The base of the unit is supported within the depression primarily by four brackets, in the form of plates l3, carried by the frame or body at the lower portion of the depression in such a manner as to support the unit at four corners. The unit is secured to these brackets by bolts I4 which extend through longitudinal slots in either or both the unit and the bracket.

The supportingand enclosing portion of the unit consists of two superimposed plates 15 and I 6. The lower or base plate i5, which may be referred to merely as the base, conforms substantially to the shape of the depression, as shown best in Figs. 1 and 4, and is supported substantially flush with the lower portion of the frame. The brackets or supporting plates l3 are shown as secured against the bottom side of the lower portions of the supporting frame. This base plate also reinforces the frame laterally, The upper plate l6, which may be referred to as the platform, provides the floor board for theoperator. ported at its forward portion directly upon the lower plate, by means of supports or braces IT. The rear edge of the upper plate or platform is hung from the upper portion of the-body, by means of hangers [8. It will be here noted that .the upper plate or platform has longitudinal slots I6 and l6 for receiving operating pedals, as will be hereinafter described, and these slots extend to the rear edge of the plate. For this reason there are provided a plurality of hangers l8 for supporting the divided sections of the platform.

The platform extends over only approximately one-half, preferably the left half, of the width of the machine, leaving an open space at the right hand side of the machine. This open space at the right is occupied by the roller-propelling engine 2|, which is shiftably mounted so as to be shifted on the base or mounting 2i in a forward and backward direction, the base or mounting being located at one side of the platform IS. The engine is adapted normally to be held in a rearwardly shifted position by a, compression spring 22.

At the opposite lateral side of the machine, between the two plates and at the forward portion of the base plate is a transmission and control mechanism 23, which is connected to the engine bya belt drive 24. This transmission mechanism is supported on the base plate I5, and the platform It may. rest on or be secured to this transmission mechanism.

The opposite end of the transmission and control mechanism is provided with a sprocket 25 which is connected, by a chain 26, with a. sprocket 21 mounted at the left-hand end of and coaxial with the forward roller 2. The chain 26 may be tightened by longitudinally adJusting the base plate on the brackets i3.

At the rear portion of the base plate is a transverse rock-shaft 28 having an upwardly and forwardly extended control pedal 29 near the left hand end. The opposite end of the shaft is provided with an arm 30 which is connected with the base of the engine 2| by a link 3|. Forward movement of the pedal 29 causes rocking of the shaft and consequent forward movement of the engine 2| against the compression of the spring 22, thereby loosening the belt 24 and breaking the positive and operative connection of the engine with the ransmission mechanism.

Intermedlat the ends of, and rotatably mounted on, the ro k-shaft 28 is a sleeve 32 carrying a brake pedal 33 which is connected to a brake band 34 on the transmission mechanism by a link 35.

In order to facilitate movement of the foot pedals, the intermediate portions thereof are adapted to extend through the aforementioned longitudinal slots It and Iii in the platform.

Though I have shown and described a particular construction, combination, and arrangement of parts and portions, I do not wish to be limited to the same, but desire to include in,-the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.
